Beit known that LRIc ARu Amos, a

citizen of the United States, and a resident of Paterson, in the county of Passaic and State. of New Jersey, have invented'certain new and useful Improvements in'. Dryin and Condensing Apparatus, of which the following is a specificationQ- h This invention relates to drying-and condensing 'apparatus.-

By the use of my invention,

sludge 0b tained from sewage water and also vegetable and other organic substances .may be separated from each other, as after be more particularly specified.

prises a tank or cylinder for thoroughly dried and said: sludgesubstances converted into a condition suitable for burning as 'afuel. Furthermore,

In the preferred form of my invention illustrated in the accompanying drawings,

g the' frame Alia-represented as of masonry having usual lower forwardly-located furnace A, conditioned in a manner which may be readily understood. Such frame is preferably saformed that when the tank or cylinder B is suitably supported thereon, a lower rearwardly leading flue B, an uptake and two forwardly'leading fines, B 3 will be provided between such tank and the frame. -The lower rearwardly leading flue Bl. together with the furnace erably have a capacity ample to bathe the lower half of said tank B. The uptake B Patented July 19, 1910.

A will prefwhich is preferably located at the rear of the tank or cylinder, receives the gases of combustion from the flue B" and delivers the same at its upper end to the forwardly leading fl-ues B B, which extend\longitud-inal-ly on opposite sides of the tank and are entirely independent of each other till they merge in a short. vertical passage 1) at the forward end of the tank, delivers to the discharge or stack 6.

The tank or cylinder is preferably so situated relatively to the frame that .it

abut-s at both sides against the adjacent surfaces thereof-at a point belowthe fines B B separating the same from" the flue B and from each other. The roofs of the fines B B are formed by the. laterally Centrally located within the tank and resting at its forward end a suitable bearing C" is .a shaft C which extends through the rear head of the-tank and rear wall of the frame a suflicient distance to permit a driving pulley c-to be fixed thereon. Preferably the portion of said shaft which spans the uptake B will be. incased in asleeve C which will provide a'protecting. or dead air space surrounding the same. bearings C in the rear wall of the frame.

That portion of the shaft C which is within the tankB carries agitating or stirring arms which are preferably alternately arranged as indicatedin Figs. 1 and 2,- for the purpose ofthoroughn'ess of operation.

which passage- Suitable are also provided for said shaft the arch plate B;

I To further promote the effectiveness of said arms, each of the same is triangular in cross-section, as shown in Fig. 5, resulting in three edges a, a, a such arms being so secured to the shaft that as the latter rotates, the edge a will be presented to the material and will cut and make a path through the same, the diverging faces an acting to further separate and spread the material.

The tank or cylinder isprovided with a charging opening B preferably located at or near the center of the upper surface thereof, and a door B is provided preferably at the forward end of such tank for the removal of the material.

From the above description, thus far, it will readily be seen that a suitable material, such as sludge, or fruit, vegetable or other appropriate matter may be introduced into the tank, the latter closed and the drying operation begun by firing the furnace. A. fuel comprised of the residuum of previous drying operations in compressed form may be employed for the purpose. The furnace being fired, the gases of combustion will circulate through the respective flues as hereinbefore indicated, thus subjecting a large proportion of the surface of the tank to the heat thereof, and producinga drying effect upon the material contained therein. This drying of the material is rendered most thorough and complete by the action of the agitating arms D in spreadin and separating the material as hereinbefore described. During such drying operation, vapors containing the elements of ammonia liquors and alcohol will be driven ofi. For the purpose of collecting, condensing and separating these vapors, I provide a pipe E communicating with the interior of the tank through its tap and preferably close to the rear end thereof. Said pipe E leads to and is connected with a condensing chamber F which is provided at its lower end with a pipe 7 communicating with a reservoir Gr. A pipe f connects the top of the chamber F with a condensing coil H which in turn may deliver to any suitable receptacle, not shown. The ammonia liquors Wlll readily condense in the chamber F and pass to and be stored within the reservoir Gr while the remaining vapors will flow to the coil H where they branch, a

tank, and collecting,

will be converted into alcohol and thereafter disposed of as may be desired.

Obviously, drying and condensing apparatus, such as that hereinabove described, is comparatively inexpensive to erect, operate and maintain, and its employment permits the material to be completely treated and utilized in the most economical manner.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. Inapparatus of the character described, the combination with a frame embodying a furnace, a. tank supported by said frame, said tank and frame work cooperating to present a lower rearwardly extending flue bathing the lower half of the tank and two upper return flues one on each side of the tank above the longitudinal center line thereof, said return fines being indeendent of each other for a major part of their length but terminating in a common discharge communicating with said branch, agitating means within the condensing and separating means communicating with the upper portion of said tank, as and for the purpose set forth. v

2. In apparatus of the character described,

the combination with a frame embodying a furnace, a tank supported by said frame, said tank and frame work cooperating to present a lower rearwardly extending flue bathing the lower half of the tank and two upper return flues one on each side of the tank above the longitudinal center line thereof, said return fiues being independent of each other for a major part of their length but terminating in a common branch. a discharge communicating with said branch, a revoluble shaft within said tank, arms triangular in cross-section secured to said shaft, andcollecting, condensing and separating means communicating with the upper portion of said tank, as and for the purpose set forth.

In witness whereof, I have signed my name to the foregoing specification in the presence of two subscribin witnesses.
